Improvement in roofing-brackets



anni effin.

JONATHAN W. OADWELL, OF SPRINGFIELD, MASSACHUSETTS.

Letters Patent No. 112,898, dated March 21, 1871.

"IMPROVEMENT IN ROOFIN`GBRAKETS.

The Schedule referred to in these mtters Patent and making part of the same.

I, J ONATHAN W. OAJJwnLL, of Springfield, Hampden county, Commonwealth of Massachusetts, have invented a new Adjustable Booting-Bracket, of which the following is a specification.

Nature and Objects of the Invention.

My invention relates to an adjustable bracket that may be used in shingling or slating roofs, or in performing any workor repairs that may be necessary on the root' of a house already completed, for the purpose of supporting the end of a scaffold, and is adj ustable, to be used with equal effect upon a roof of any inclination; and

The object of my invention is to provide a light, portable bracket for carpenters and others, that can be at once adjusted in place to hold' the scabldng, thereby saving the time required in ordinary cases to construct the same, and during which time a number of hands are Aoften idle waiting for. its completion;

and a bracket, also, that can be used upon either slate or shingle roofs and be removed without leaving any nail-holes for the admission of water.

Description of Accompanying Draung.

Figure I shows a side view of one of my brackets in position upon a shingle roof.

Figure II shows a plan view, with the hook used to fasten it to a slate roof.

Figure III, a detail view of part of the tongue, showing the shoulder on saine.

General Dscription.

The general shape of my bracket is triangular, and consists of the two bottom pieces A A, which form the base ofthe bracket, and are designed to rest directly upon the roof.

Between these two pieces, at one end, at a, is hinged the piece B that supports the scaffolding, while the pieces A A are connected at their other ends 'by pins c c c, Sto., placed at any desirable distance apart.

The end b of the piece B is let into and 'hinged to the'end of the piece F, forming the third side of the triangle.

This piece F has a stock removed from one end to form a tongue or pawl, L, with shoulders on each side, the pawl catching against one of the pins c c c, &c., and the shoulders coming against the top ofthe pieces A A, so that, as shown in Fig. I, any inclination desired can be given' to the piece B, supporting thescaolding by changing the piece F from one pin c to anotherf 'Attached to one end of the bracket, on its lower side, and projecting beyond it, is the sheet-metal plate G, provided at one end with the key-shaped holes j f, andthe circular one, g. These peculiarly-shaped lholes in the plate G enable the 'bracket to'be nailed to the root' on that part of the shinglethat will be covered by the butts of the next s ucceding la fer of shingles, as the nails holding the bracket are riven throughtlje smaller part of the holes f and when it is desired to remove the bracket it is only necessary sto slide it up the roof until the headsof the nails-- come opposite the larger part of the holes, when, by lifting the bracket at oneend slightly, it can be drawn out from beneath the butt of the shingle, and a few taps of the hammer on the shingle above drives the nails out of the way into the roof.

I claim this as one great advantage in my bracket, as the ordinary way of securing brackets by nailing them to the outside of the roof, and leaving the nails in upon removing the bracket, or the holes but imperfectly plugged up, is liable toY many objections.

Upon the other end of the bracket from which the plate Gr is fastened is attached a cross-piece, W, which is necessary when the hook R, fastened to the circular hole g', is used, as in the case of rooting with slate, because, as the bracket cannot be nailed to the roof, it Ymight otherwise upset. This piece Wis screwed to pieces A A, and can be removed, if desired, for

shingling.

' Claim.

G, having the holes f 7 and g, and hook R, and cross.

piece W, the parts being combined and arranged substautially in the manner and for the purpose shown and described.
